Each contains call is loop over regexp list, relatively expensive.
Taking that into account, please:
1. use lazy eval of boolean
2. remove no_sanitize?
```
return NoSanitizeL->containsType(Mask, Ty.getAsString()) ||
!NoSanitizeL->containsType(Mask, Ty.getAsString(), "sanitize");
```
Then the first call `NoSanitizeL->containsType` will be enough in most cases.
